Hi all,

After merging the xen-tip tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/char/tpm/xen-tpmfront.c: In function 'setup_ring':
drivers/char/tpm/xen-tpmfront.c:203:7: warning: passing argument 2 of

Caused by commit 1b1586eeeb8c ("xenbus_client: Extend interface to
support multi-page ring").

I have used the xen-tip tree from next-20150410 for today.


Sorry for this issue, I missed the xentpm-front.c file in that patch.
(Original patch from Wei Liu already included the right modification which didn't exist in Paul's.)

Attached patch should fix this build failure.
